The F Sport also offers an available handling package, which includes Lexus Dynamic Handling (variable gear ratio steering and active rear steering), an active stabilizer, and sport-tuned air suspension with rapid height function.

The F Sport makes no changes to the LS 500 powertrain choices of a 3.5-liter twin-turbo V-6 or 3.5-liter V-6 hybrid, which promise 060 acceleration of 4.5 and 5.2 seconds, respectively. The twin-turbo engine makes 415 hp and 442 lb-ft of torque and comes mated to Lexus' first 10-speed automatic transmission.

The F Sport is also about putting on the appearance of track-tuned wildness—as seen with its racy rocker panels and trunk moldings.

Although it might take some keen eyes to notice, the LS 500's spindle grille has been altered for the F Sport model—requiring five months of computer-aided design work. Lexus says there are 7,100 individual surfaces to the F Sport grille, compared to 5,000 for the base model. But who's counting?

Inside, the front seats receive more side bolstering in case inspiration strikes and the driver decides to lay into the aluminum accelerator pedal. (The brake and footrest pedals are also made of aluminum.) The steering wheel likewise gets the upgrade treatment, and the instrument cluster slides to reveal more information depending on driving mode—a trick borrowed from the LFA supercar.
